IMPROVEMENT IN PLANING-MACINE.

The Schedule referred to in these Letters Patent and making part o! the same.

ence being had to the accompanying drawings forming part oi' this specification, in which- Figure l shows a vertical cross-section of the supportiug-frame, with our improvement; and

Figure 2 is aver-tical central longitudinal section of the same.

, Similar letters of reference indicate like part-s.

This improvement relates to a new construction and arrangement of the parts for raising and lowering the table or bed oi' wood-plancrs, whereby the adjustment of the bed is made more readily than by the ordinary methods, and a simple and subst-autialconstruction ofthe parts is obtained, as hereinafter more fully described.

In the accompanying drawings- A A a is the frame-work, iu which is mounted tlie vertically-adjustable. table or bed B. i

The hed B is raised and lowered by a single screw, D, placed under its center, the screw being fixed rigidly in the bottom piece a oi' the frame, and a hand-` wheel nut, E, traveling on said screw, to carry the bed vertically.

The bed B has rollers c c, as ordinarily, and on its lower side is provided with a sleeve or collar, b2, which travels on the` upper part of the screw, and the table has also a yoke, b b, fig. 1, which roaches down below the nut E, and embraces the base or lower part ofthe screw by mcans of a collar, b1, the said collars bland 112 acting as guides to steady the table in a vertical position within the frame A A.

By this construction the adjustment of the table or bed B is made with the greatest facility, and a strong' and simple `.construction and arrangement ofthe parts are obtained.

We do not claim, broadly, the .use of a single screw for raising and lowering the bed of a planing-machine, as that is not new; but having thus described our iu- Ventiou,

Vhat we claim as new, and desire to secure by Letters Patent, is- Y,

The screw D, rigidly secured in the framing A a,

and carrying the bed B and hand-wheel nut E, said
